Unity[Android] AdMob error

Hey, I nearly finished my app and wan't to add AdMob ads but if I want to export the project there are always showing up some errors which I can't fix(or don't know how to. Even didn't find something useful in the web)

So, here are the errors:

 CommandInvokationFailure: Failed to re-package resources. See the Console for details.

And the other error

 Google.JarResolver.ResolutionException: Cannot find candidate artifact for com.android.support:appcompat-v7:23.1.0+

Does anyone know this error because I watched some tutorials and these errors never occured by them.(My Unity version: 5.3.4f1)
